This source's evidence 🎬

Source verdict

The reviewer concludes that both the Galaxy Watch 9 and Watch Ultra 2 are "nice improvements" and "solid wearables" that continue Samsung's strong presence in the Wear OS market. They suggest these are a "better buy than last year" and offer an element of rugged quality over competitors like the Pixel Watch.

About this source

This review provides an early look at the Samsung Galaxy Watch 9 and Galaxy Watch Ultra 2, focusing on design changes, battery improvements, display brightness, and new fitness features. The reviewer offers initial impressions on both wearables, highlighting the Ultra 2's advancements while noting the Watch 9's similarity to its predecessor. It also discusses software integration like Gemini and new wearable-specific features.

Review notes

A significant upgrade over its predecessor, Samsung's Galaxy Watch Ultra 2 establishes itself as a strong contender in the rugged smartwatch market. It boasts an impressive 5,000 nits peak brightness display, making it incredibly visible in any lighting, and packs a massive 800 mAh battery which hints at multi-day usage, though exact longevity still needs testing. However, the bio-active sensor lacks upgrades, and the limited color options might disappoint some users who prefer more aesthetic choices. If you are an outdoor enthusiast, diver, or someone who needs a highly durable smartwatch with advanced tracking features, this device is an excellent choice. But if you prioritize cutting-edge health tracking sensor improvements, you might want to consider other options.

What the reviewer liked

  • 12% thinner than previous version
  • Massive 800 mAh battery
  • Vastly improved maximum brightness (5,000 nits peak)
  • IP69K rating and EN13319 diving certification for impressive underwater capabilities
  • Engages water lock automatically when submerged
  • Future Mares app integration for advanced dive metrics (descent speed, decompression guidance)
  • Enhanced trail running tracking with real-time GPX route guidance
  • AI-powered hydration guidance function, better than generic reminders
  • Raise to talk feature for Gemini integration
  • More seamless, integrated metal design with a flatter profile
  • Lighter than the original model

What the reviewer criticised

  • Limited color options (only silver or gray, no matte black)
  • Bio-active sensor appears to have seen little to no upgrades
  • Blocky shape and aesthetic might not appeal to everyone, especially those who disliked the previous design shift
  • Multi-day battery life (3-6 days) is yet to be fully confirmed through extensive testing
  • Lacks the much-loved rotating bezel of some other Galaxy Watch models
